In the matrix $A=\begin{bmatrix}2 & 5 & 19 & -7\\35 & -2 & \frac{5}{2} & 12\\\sqrt 3 & 1 & -5& 17\end{bmatrix},$ write the elements $\;a_{13},a_{21},a_{33},a_{24},a_{23}$ \[\]

Question

$\begin{array}{1 1} a13 = 19 a21 = 35 a33 = -5 a24 = 17 a23= 5/2 \\a13 = 19 a21 = 5 a33 = -5 a24 = 12 a23= 5/2 \\a13 = 19 a21 = 35 a33 = -5 a24 = 12 a23= 5/2 \\ a13 = 12 a21 = 35 a33 = -5 a24 = 12 a23= 5/2\end{array} $
